M45PE40 Datasheet



The M45PE40 is a 4-Mbit (512 Kbit x8 bit) serial paged flash memory accessed by a high speed SPI-compatible bus.The memory can be written or programmed 1 to 256 bytes at a time, using the page write or page program instruction. The page write instruction consists of an integrated page erase cycle followed by a page program cycle. M45PE40 Features • SPI bus compatible serial interface• 75 MHz clock rate (maximum)• 2.7 V to 3.6 V single supply voltage• 4-Mbit page-erasable flash memory• Page size: 256 bytes: – Page write in 11 ms (typical) – Page program in 0.8 ms (typical) – Page erase in 10 ms (typical)• Sector erase (64 Kbytes)• Hardware write protection of the bottom sector (64 Kbytes)
